nnvnnsnsnn crmnnnnv Application filed October 21,1922. 1 Serial No. 595,911.

To all whom it may concern:

Be it known that I, HARVEY W. GUTSHALL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain-new and useful Improvements in Reversible Cylinders, of which the following is a specification, reference being had to the accompanying drawings, and to the reference characters marked thereon, which form apart of this specification.

This invention relates to improvements'in cylinders for internal combustion engines and more particularly to that type of engines used on platform inotor cars used largely for maintenance and inspection work on railways, although adapted forother uses.

Heretolore, in order to conform to the necessity oi. placing thecylinder on either the right or the' left hand side ofthe drive crank, it has been the custom to make a right and a left hand set of patterns and to cast the cylinders, ri'gl'i'ts and lefts. This isnot only expensive but it requires having on hand, in stock, a quantity of both right and lefthand cylinders for purposes of repairs and renewals-together with right and left handsets of tools, temple-ts,'&c., to finish the cylinders for use.

The principal object otmy invention is to obviate these objectionable features and expenseand to produce a type of cylinder which is reversible, so that it may beused upon either the right or left hand side of the drive crank.

Another object "of the invention is to produce a cylinder havinga duplex inanifold, either half of which may be used as required. I

Still another "leature oi thei'nv'ention is to providemeans, such as a removable deflector c over, over the cylinder exhaust open ings, whereby the"exhaust in'ay be deflected in the desired direction. I

These and other objects and. advantages ofthe invention will becoi'ne manifest as I proceed with my specification.

In that form in which I have chosen to illustrate the invention in the accompanying drawings:

Figure 1 is a side elevation of a typical cylinder for an internal combustion engine, constructed in accordance with my inven tion.

Figure 2 is a transverse vertical sectional view, of the cylinder with a defiectorpl-ate attached, the section being taken in the plane of'the dotted lineQ 2 of Figure 1.

, Figure 3 is a perspective view of the deflector cover, detached,

Figure 4: is a View similarto the section shown in Figure 2, and in the same plane, but showing the cylinder turned about its central longitudinal axis so as to beylocated on the side of the drive crankshaft opposite to the side shown in Figure 2. Thus'Figures 2' andl showthe reversible characterof the cylinder for right and left, hand use as desired. I

Referring to the drawings: A represents the cylinder as awhole, comprising the cyl inder body 1 having the usual concentric externally located rings or fins 2, a crank case 3, and inlet and exhaust ports land 5, through the wall of the body 1-. Surrounding the inlet portsis a gas chamber 6 provided with diametrically opposedscrew threaded passageways 7, 8, through hub supports 9 and 10, cast integral with the body 1, To one of thesehubs, say 9, a carburetor C is secured, theopeningB of the hub 10 being closed by an ordinarysc-rew plug D. Upon the outside of the body l, above and below the horizontal axis of the body 1, are two lugs 11 and 12 extendinglengthwise of the body and outwardly therefrom. Each lug has a centrally located half round re cess 13 in its outer edge. These lugs are located, as shown, above and belowthe exhaust ports 5. a I i a In Figure 3, I have shown detache'dthe cover and deflector plate designa-tedyas a whole, by the letter B, and comprising a back'wall 14, two side walls 15, 15, all connected at the top by the transversely arranged and downwardly projecting lug 16. At their lowergportion, the walls 15 are joined by a relatively narrow, transverse front wall 17, the upper margin or edge of which is provided with a centrally located half-round recess 18. The lower margins of the back wall 14, side walls 15,15, a'ndtront Wall 17, define the exhaust o iienin'g 19 ofthe deflector B. On the cylinder body 1 on each side of the exhaust ports 5 is an outstanding circumferential rib 20, which ext-ends, however, only from the lug 11 to the lug 12. The outer edges of these ribs 20 are formed on an arc concentric with the cylinder surface. The front margins, 21, 21, of the side walls 15 of the deflector, are shaped to conform to and rest upon the outer surface of the cylinder body 1. The two side walls 15, 15, are spaced apart a distance sufficient to nicely fit over and embrace the parallel ribs 20, 20, when the deflector is positioned upon the cylinder. Upon the inside of each of said deflector side walls and at a proper distance from the margin 21 is a lug or shoulder 22 against which the outer edge of the ribs 20, 20, abut when the deflector is in place.

To hold the deflector in place, the hook or projecting lug 16 is placed over one of the lugs, 11, 12, (say the lug 11), as shown in Fig. 2, and the deflector seated against the cylinder body. This will bring the lower edge of the lug 12 and the upper edge of the deflector front wall 17 into'proper contact, with their respective half-round recesses 18, 18, in register to form a round passageway for a fastening bolt 28. This bolt will have a head 24 and a retaining nut 25, which form shoulders to embrace the side faces of the lug 12 and front wall 17, and securely lock them together.

By this construction it will be clear that the exhaust will pass through the ports 5 to the interior of the deflector B, be deflected downwardly and out through the bottom opening 19.

When the cylinder A is reversed with respect to the crank shaft, from the position shown in Fig. 2 to that shown in Fig. 4, the bolt 23 is unfastened and removed, the deflector being hung at its top over the lug 12, which is now on top, and the wall 17 bolted to the lug 11. It will be understood, of course, that when so reversed, the carburetor C and the closure or plug D will also be reversed, from engagement with the lugs 9 and 10 to engagement with the lugs 10 and 9, respectively.

It will be understood, however, that the one part of the manifold will not always be closed by the plug D, as for instance, where two fuel supplies are desired, a second carburetor would be used instead of plugging one of the passageways 7 or 8.

I claim as my invention:

1. In a reversible engine cylinder having a duplex manifold and exhaust ports opposite the manifold ports, a hollow, open bottom deflector member, means for removably engaging said deflector with the cylinder to cover the exhaust ports, and means for locking the deflector to the cylinder, said removable engaging means including interlocking lugs on the cylinder and deflector.

2. In a reversible engine cylinder having a duplex manifold and exhaust ports opposite the manifold ports, a hollow, open bottom deflector member, means for removably engaging said deflector with the cylinder to cover the exhaust ports, and means for looking the deflector to the cylinder, said locking means including complementally notched parts on the deflector and the cylinder, and a headed bolt.

3. In a reversible engine cylinder having a duplex manifold and exhaust ports opposite the manifold ports, a hollow, open bottom, removable and reversible deflector member adapted to cover either of the exhaust ports, and means for locking the deflector to the cylinder, said removable, reversible and locking means including interlocking lugs on the cylinder and deflector.

4:. A reversible engine cylinder provided with a duplex manifold, a pair of circunr ferentially located ribs, one on either side of the exhaust ports, lugs extending longitudinally of the cylinder and joining the ends of said ribs, in combination with a hollow, open bottom member adapted to surround said lugs and to cover the exhaust ports, and means for removably securing said member to the cylinder.

5. In an internal combustion engine, a cylinder, exhaust port or ports through its wall, a pair of circumferentially extending ribs on the outside of the cylinder, one on each side of said exhaust port or ports, a

pair of radially and longitudinally extending lugs on the cylinder between said rib ends, one at each end of the exhaust port or ports, the outer face of each lug being centrally recessed, in combination with an open bottomed, removable deflector hood member, the side walls of which have curved faces to fit upon the cylinder and to fit over said circumferential ribs, a downwardly projecting lug or hook member on said deflector adapted to fit over and engage one of the longitudinally extending cylinder lugs, a front wall memher on the deflector, one edge of which is adapted to engage the edge of the other cylinder lug and is provided with a recess complemental to the recess in said lug, and a locking bolt in said registering recess.

In testimony that I claim the foregoing as my invention I afiix my signature in the presence of two witnesses, this 12th day of October, 1922.
